[0002] In the field of gravity mineral processing, spiral sluices, as a classic gravity separation device, are widely used in the separation of minerals with large density differences, such as tungsten, tin, and ilmenite.

[0003] Traditional spiral chute devices typically employ a single-channel fixed structure, which presents the following technical bottlenecks: First, the uniformity of slurry distribution is insufficient, leading to fluctuations in sorting accuracy; second, it is difficult to dynamically adjust sorting parameters according to mineral properties, limiting the adaptability of the equipment. Therefore, there is an urgent need to develop a new type of spiral chute device that combines efficient sorting with flexible control. Utility Model Content

[0004] In order to overcome the shortcomings of existing equipment in terms of insufficient uniformity of slurry distribution and dynamic adjustment of separation, the technical problem of this utility model is to provide a spiral chute device for high-efficiency mineral processing.

[0005] The technical solution is as follows: A high-efficiency sluice box device for mineral processing, the device consists of two ore-dividing mechanisms and a conveying mechanism.

The conveying mechanism includes a feed trough, a screw conveyor, a diversion trough, an inlet, a baffle plate, a rotating rod, an electric push rod, and a second guide pipe. The screw conveyor is installed at the bottom of the feed trough, and the other end of the screw conveyor is connected to the diversion trough. The diversion trough has an inlet near the screw conveyor. The baffle plate is rotatably connected inside the diversion trough, and a rotating rod is fixedly connected to the rotating shaft of the baffle plate.

[0011] 1.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] Example: A high-efficiency spiral chute device for mineral processing, such as... Figure 1-4As shown, the device consists of two ore-separating mechanisms and one conveying mechanism. The ore-separating mechanisms include a filling tank 1, a first guide pipe 2, a fixed frame 3, and a chute 4. The chute 4 is fixedly connected to the fixed frame 3, and the filling tank 1 is fixedly connected to the top of the chute 4. The first guide pipe 2 is connected to the side of the filling tank 1. The conveying mechanism includes a feed chute 7, a screw conveyor 8, a diversion chute 9, an inlet 901, a baffle 10, a rotating rod 11, an electric push rod 12, and a second guide pipe 13. A screw conveyor is installed at the bottom of the feed chute 7. The other end of the conveyor 8 is connected to a diversion trough 9. The diversion trough 9 has an inlet 901 near the screw conveyor 8. The inside of the diversion trough 9 is rotatably connected to a partition 10. A rotating rod 11 is fixedly connected to the rotating shaft of the partition 10. An electric push rod 12 is rotatably connected to the outside of the diversion trough 9. The other end of the rotating rod 11 is rotatably connected to the telescopic shaft of the electric push rod 12. The bottom end of the diversion trough 9 is connected to two second conduits 13. The two second conduits 13 are respectively connected to a filling tank 1.

[0021] like Figure 1-2 As shown, a movable plate 5 is installed on the bottom chute 4, and a diversion block 6 is slidably connected to the movable plate 5. The diversion block 6 is fixed to the movable plate 5 by bolts. By precisely adjusting the diversion block 5, the recovery rate of the target mineral can be improved, the sorting accuracy can be increased, and the fine sorting requirements of different minerals can be met.

[0022] like Figure 1-2 As shown, the cross-section of the diversion block 6 is wedge-shaped, and its position adjustment range covers the full width of the chute 4. The wedge-shaped hydrodynamic structure can reduce the resistance of slurry diversion. The full width coverage adjustment range can adapt to the stratification trajectory of minerals with different densities. The rigid connection fixed by bolts ensures the stability of the position after adjustment, avoids the drift of sorting parameters caused by vibration, realizes the precise control of the sorting boundary grade, and ensures the consistency of sorting indicators.

[0023] like Figure 1-2 As shown, chute 4 adopts a modular segmented design, with each segment connected by flange bolts. The modular structure facilitates transportation and on-site hoisting. The flange bolt connection, combined with wear-resistant sealing strips, shortens the replacement time of a single chute 4 segment, significantly improving the continuous operation rate of the equipment. At the same time, the modular design supports adding or removing chute segments as needed to adapt to different process requirements for different throughput.

[0024] like Figure 1-2 As shown, the dual-separation mechanism is symmetrically arranged on both sides of the conveying mechanism to form a parallel separation system. The symmetrical arrangement forms a dual-station parallel separation system, which increases the processing capacity by 1 times compared to a single mechanism. The independently controllable dual-separation mechanism can simultaneously process slurries of different properties or execute different separation parameters. The slurry flow direction can be quickly switched by switching the baffle 10 through the electric push rod 12, which greatly improves the equipment's adaptability to multiple mineral varieties.

[0025] like Figure 1-4As shown, the inner wall of the filling tank 1 is provided with an anti-fouling coating. The coating is made of nano-ceramic material with a surface roughness Ra≤0.8μm. The nano-ceramic coating has an extremely low coefficient of friction and chemical inertness, which effectively prevents the adhesion and scaling of sticky substances in the slurry, reducing the cost of manual cleaning and downtime losses.

[0026] Workers pour the slurry into the feed trough 7. Under gravity, the slurry enters the screw conveyor 8, and is pushed at a stable flow rate by the screw blades of the screw conveyor 8 to the diversion trough 9. After entering the diversion trough 9 through the inlet 901, the baffle 10 is initially at a set angle. The slurry flows through the unobstructed second conduit 13 into the corresponding hopper 1 of the ore sorting mechanism, and then through the first conduit 2 into the chute 4. Inside the spiral chute 4, the slurry is subjected to the combined effects of gravity, centrifugal force, and fluid resistance, achieving centrifugal stratification based on the differences in density, particle size, and shape of the mineral particles—high-density particles move along the inner side of the chute 4, while low-density particles migrate to the outer side. By adjusting the position of the diversion block 6 on the moving plate 5, the interception position of particles of different densities can be precisely controlled, achieving efficient separation of the target minerals.

[0027] When it is necessary to switch sorting parameters or process slurries of different properties, the servo system of the electric push rod 12 is activated. The telescopic shaft of the electric push rod 12 moves at a preset angle, driving the partition 10 to rotate around the shaft via the rotating rod 11. This causes the partition 10 to block the original inlet of the second conduit 13, while simultaneously exposing another second conduit 13. At this time, the slurry conveyed by the screw conveyor 8 flows into the filling tank 1 of another sorting mechanism through the newly opened second conduit 13. The position of the diversion block 6 of the chute 4 of this sorting mechanism is adjusted to achieve independent sorting parameters for the two stations. Throughout the process, the operator automatically optimizes the screw conveyor speed and the angle of the partition 10 according to the actual situation to ensure maximum sorting efficiency.

[0028] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
